I now prefer the teardrop for the exterior feel/comfort factor; it fits the hand better than the wedge, I think. When I can, though, I change the switch in either for a cheaper switch from a PC mouse - quieter, easier clicks. The Plus' brick mouse always irked me - it usually squeaks, and you have to press so much harder than with later mice. Or that's the impression.
Mouse peeves:
- rollers so encrusted with crud (skin-dust, pore-grease, cat hairs, etc.) that you feel like you're passing your hand over a stuccoed surface when you sweep the mouse from side-to-side;
- eleventeen-button mouses; and,
- glide-shmutz, the layer of the (presumably) same crud as found on rollers that, in this instance, causes the mouse to sweep so sluggishly it's an effort to move it at all.
The scroll-wheel is highly over-rated. In fact, everything beyond a single button is over-rated.
I'm currently using a Kensington ADB TurboMouse trackball (no right-click) and an indented puck mouse on my Beige tower (still with it!). Somewhere on the desk in front of me, beneath several geological strata of miscellaneous cables, papers, and bits and pieces of everything, I have a scroll-wheel USB Mouse-in-a-Box (trash-picked, but known to work, and not much missed), and a swoopy-n-swishy Logitech scroll-wheel dingus with that strange little button under your right thumb... I'd installed the software for the latter, but got bored with it...
I've recently pulled the trackball from a wrecked PB1x0 and have briefly tested it as an ADB device. Worked fine until one or two of my hastily-soldered connections on the underside of the board gave out. Current plan is to solder a section of ADB cable to a ribbon cable which will, in turn, be properly inserted into the little socket on the upper side of the circuit board... Then there's the matter of making the section of the PB's wrist-wrest flow gracefully down to the surface of the desk (probably by kerfing the underside somehow, and notching the forward/near face so that I can bend things to my will)...
Projects. Too many projects.
